I'm a very tactile and oral stimmer (amongst other things) and these are great relief and much better way to redirect texture-touch needs than something destructive (cuticle picking, etc) which has been my default for decades. They're wonderfully subtle if need be (running my thumb along the bumps while it's in my jeans pocket or under the desk, etc). Plus it's a fun flexy-fidget toy as well that can be used one handed to help the rest of my attention focus elsewhere. The bump variety is great, I find myself switching between all four textures naturally, in both parallel and perpendicular directions. Plus the tiny bumps are great little "spikes" to press into for a more sharp feeling (but no where even close to painful). Just ticks that sensory box. Now I try and make sure I've always got one with me just for those moments.
